I order of bang for the buck...
1. K&N Air Filters (<$100)
2. ECU "chip" mod ($300-$700 depending on company)
3. Exhaust mod ($500-$1000 ???)
4. airbox/intake mod ($500-$1000 ???)
5. aftermarket Supercharger (~$12k)
6. StarTech/RennTech/etc. ($15k and up???)
That ordering is solely MY opinion, based on what I've seen people posting here since ~January.
Set aside a weekend and read all the threads in the Tech/Mods section if you want to see what people have tried, results, what didn't work, what did, what looks like it'll never work, what might happen if enough people express interest, etc.
